Good day. I am facing issue with creating a GlobalVariable. I already have an extern for that global in a header file to use it in the following way
extern const void* DATA_TABLE;
And with a LLVM PASS, I am trying to create this array with the same name and with initializer. So, I have following:
GlobalVariable *gvar_data = new GlobalVariable(
M, blockItems->getType(), true, GlobalValue::CommonLinkage,
I am not sure if I am using the correct Linkage or not.
The pass has failed to complete it. Here is the runtime fault. Any guess what I am doing incorrect?
'common' global must have a zero initializer!
[10 x i8*]* @DATA_TABLE.1
LLVM ERROR: Broken module found, compilation aborted:::::::::!
